It is best to start with known processed nutrients until you know what you are doing. I have used all the available organic type nutrients made for hydro, but I must tell you. GH 3-part outperforms even the best organics(Pure Blend Pro) in Hydro.

It is better to learn hydroponics before you introduce variables which you might not understand. go GH3-part and you will have a successful grow that you can build knowledge off of, and then do an Organic grow, and you will see the difference...3-part in small bottles is under 30 bucks...goodluck
